Introduction
Results
WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) is a practical, generic assessment instrument that measures health and disability. It has sound theoretical underpinnings, good psychometric properties and numerous applications in different participant groups.
WHODAS 2.0 consists of six domains that measures health and disability:
Cognition
Mobility
Self-care
Getting along
Life activities
Participation
The amount of difficulty when doing the tasks associated with the domains are ranged from 1 to 5 (from none difficulty to extreme or cannot do)*.
Test-retest reliability
for the total score of WHODAS 2.0 was rs (p<0.01),
for the domains rs (p<0.01).
Inter-rater reliability
for the total score was rs (p<0.01),
for the domains rs (p<0.01).
Internal consistency
for the whole assessment of WHODAS 2.0 was Cronbach’s Alpha 0.836,
for the domains:
Cognition 0.787,
Mobility 0.710,
Self-care 0.846,
Getting along 0.722,
Life activities 0.866
Participation
Aim
The aim of this work was to test the:
inter-rater reliability;
test-retest reliability;
internal consistency reliability
of the Latvian version of WHODAS 2.0.
Conclusions
The results of reliability testing for Latvian version of WHODAS 2.0 were found to be good to excellent. It can be assumed that the Latvian version is reliable to use when measuring the limitations on activity and restrictions on participation experienced by an individual.

Materials and methods
Twenty participants:
aged (Me 18, IQR=19-17) years,
with diagnosis cerebral palsy (CP),
without cognitive impairment participated.
Inter-rater reliability was tested between two physiotherapists with more than five years of experience in work with youth with CP, test-retest reliability was done with having one week between the two assessments, internal consistency was tested for the whole assessment and also for each of the six domains (Cognition, Mobility, Self-care, Getting along, Life activities, Participation) of WHODAS 2.0.
